 * Could someone please explain this piece of code for me:
 * `var bottomPos1 = $('#top-slider').outerHeight(true)-$("#main-header").height()-
   15;`
 * I want to change the position.
 * Its for the placement of a image on my home page, but im not good with JS so 
   I dont know what to do to change the position of my image.

 * This also seems related:
 *     ```
       $("#top-slider").append('<img class="stamp">');
           $(".stamp").attr("src",templateDir+"/img/Klarna_stamp.png");
       ```

 * > var bottomPos1 = $(‘#top-slider’).outerHeight(true)-$(“#main-header”).height()-
   > 15;
    - Get the height of the slider (a)
    - Get the height of the header (b)
    - Subtract the height of the slider (a) from the height of the header (b)
    - Subtract 15 from the total sum (c)
 *     ```
       (a - b) - c
       ```

 * Thank you! Never would have guessed that. So if I wanted to move the position
   upward, how would I go about doing that?

 * You can change the height of the header, change the height of the slider or modify
   that code. Or rewrite your own.

 * I see, I guess in this case Im not sure where the #main-header is located. I 
   have only done PHP and CSS programming before.
 * I cant find the #main-header in the JS file atleast.

 * I think I dont want to change the #main-header, because it might effect other
   things on the site. I just wish there was a simpler way to write the code.

 * Actully playing with the code this seems to be the only relevant code:
 *     ```
       $("#top-slider").append('<img class="stamp">');
       $(".stamp").attr("src",templateDir+"/img/Klarna_stamp.png");
       ```
   
 * So I wrote the wrong code in the beginning. So how can I move the image further
   up with this code?

 * Position further up.. We need to see the page you’re talking about.
